Call 110
Get prepared

something that can float on the water
a flashlight that provides light when there’s no electricity available
a phone that you can use to communicate with others
Find a Way Out
So you’ve decided to get prepared. Now let’s collect the things you need for evacuation (疏散).
Now you
choose to
Find a Way Out
stay at the place you live
evacuate to areas which are not flooded
Your disaster kit is ready, and the rain hasn’t stopped yet.
Use your phone that can communicate with the outside and stay updated.
Have food and water that is safe if you’re hungry or thirsty.
Use the flashlight that provides light only when necessary.

Applying the Rules
part 3
For people who love the sun, summer is a time of fun. But for people whose houses were submerged by the super flood that hit Zhengzhou in July, 2021, that summer was a time of great sadness. The floods killed 302 people, left 50 missing, and forced the evacuation of hundreds of thousands of people.
Practice
Amy wrote a story about what happened that day. Fill in the blanks for her.
The victims to whom the flood brought death or great loss were mainly in Henan province. In the days that have passed since then, much has been done to make things better and help the thousands of people whose homes were destroyed, although the sadness will never leave those whose summer now marks the death of a loved one.
Practice
So, the massive flooding has passed;
fortunately, everyone was safe and sound at last.
However,
what has the flood left to us
To wonder, and to ponder…
Reflection
Pictures
Here are two online posts after the flood.
Here are some original pictures by an artist who has experienced the flood.
